TELEGRAPH-POLE AND THE LIKE.

To all whom it may concern:

Be it known that I, Baoonmcn IIASKELL, a citizen of the United States,residing at Franklin, in the county of Venango and State ofPennsylvania, have invented certain new and useful Improvements inTelegraph-Poles and the Like, of which the following is a specification.

The present invention has to do with the construction of metallic polesdesigned especially for telegraphs or other overhead wire supports, andparticularly to a type of such pole wherein a series of upright legs areheld in proper spaced apart relation by a series of transverse bandssecured thereto at proper intervals. v

The matters of invention in the present instance relate to aconstruction whereby I am enabled to securely and rigidly bind the saiduprights and transverse bands together without the use of bolts, rivetsor any like fastening means having a tendency to weaken the structure.

The invention will be clearly understood from the following detaileddescription taken in connection with the accompanying drawings and thematters of novelty will thereafter be particularly pointed out in theappended claims.

Referring to said drawings: Figure 1 shows a side elevation of anassembled pole constructed in accordance with the principles of myinvention. Fig. 2 is a transverse section on an enlarged scale, the sameshowing a transverse band and locking devices in elevation. Fig. 3 is anenlarged detail side elevation partly broken away to better show thefastening means. Fig. 4 is a detail perspective of a filling blocksection used with one form of the invention. Fig. 5 is a detail showingthe assembled fastening in the same form of the invention. Fig. 6 is adetail of a wedge also employed in the same form of construction. Fig. 7is a detail showing a modified form of the assembled fastening. Fig. 8is a detail showing a further modified form of the same. Figs. 9 and 10are detail perspective views of the filling blocks employed with thefogms of Figs. 7 and 8 respectively, and Fig. 11 is a detail showing astill further modified form of fastening means.

The uprights or longitudinal members 1 are preferably three in numberand as shown are formed into U-shape from bar stock. The transversebands 2 are likewise formed Specification of Letters Patent.

of plate or sheet material of suitable width and may be dished orcorrugated as at 3 to attain greater rigidity. They are preferablysubstantially triangular as shown and are provided with pockets at thecorners to receive the uprights. These pockets may be formed from thestock of the band itself, and proper straps 5 may be employed to closethe mouths of said pockets, or as shown in Fig. 5 the said straps may besecured exteriorly of the band and themselves form the pockets as (i. Ineither of these forms the said straps are preferably secured to thebands by welding or like molecular union and without the use of bolts orlike fastening means. I will now proceed to describe the improvedfastening means which I employ to securely lock said uprights and handstogether. The devices for this purpose are illustrated in one form inFigs. 1 to (3, those of Fig. 5 being shown as substantially of this formthough as before explained the strap arrangement is different. Fillingblocks 7 and S are fashioned to substantially till the aforesaidpockets, the same having in their abutting faces complementary portionsof a recess to receive a wedge block 9 which is inserted so as to exertits principal wedging action in separating the blocks and pressing thesame against the sides of the upright 1. The outer sides of said blocksare formed with a wedging bulge 1.0 which, as will be clear when theblocks are forced home, eo-acts with the adjacent flat face of thepocket and by slightly distorting the same exerts a drawing in forceupon the sides of the U upright. The said flat pocket portion may beconcaved as at 11, Fig. 5 or the same may have a dished out centralportion 12 to eo-act with the wedge surface as shown in Figs. 7 and 8.

Figs. 7 to 11 show constructions which act in a like manner as abovedescribed, the same differing mainly in the construction andarrangemei'it of the wedging element. As shown in Figs. 7 and 9 thewedging element fills all the space between the blocks 7 and 8, by meansof an extension 14 and has an enlarged wedge head 13 which carries awedging surface 15 on its face similar to the bulge surface 10 beforedescribed. In Figs. 8 and 10 the wedge element is of T form, theextension 16 with enlarged head 17 filling the space between the blocks7 and S, and a transverse portion 18 thereof being disposed between theends of the U and the fiat strap side of the pocket. As shown thisportion 18 is provided with a wedging bulge 19 similar tothose abovedescribed. As shown in Fig. 11 the blocks 7' and 8 have a recess formedin their outer endsto receive a wedge 20 similar to the wedge 9' abovedescribed.

It will thus be seen that in each of the several forms illustrated Iprovide means wherebythe upright and band are strongly and efi'ectivelydrawn and clamped together by. pressure exerted throughout the area ofcontact of said members. I

I do not claim broadly the matter herein shown and. described, but havevmade the same the subject of a separate and co-pending application,Serial No. 527,427, filed Nov. 11, 1909.

Having now fully described my invention what I claim as new and desireto secure by Letters Patent is as follows:

1. A pole comprising uprights, transverse bands having pockets toreceive said uprights, straps secured to said bands adjacentsaid-pockets, plural filling members for each pocket, means toexpandsaid filling members and means to react against said straps soiasto exert clamping pressure throughout the areaof cont-act.

2. A pole comprising uprights, transverse straps, all arranged so as toexert clamping pressure throughout the area of contact.

8. A pole comprising longitudinal members, of U section, transversebands having pockets to receive said members, straps secured to saidbands adjacent said pockets, plural filling blocks for said pockets andmeans to expand said blocks against the walls of said pockets and pushthe straps toward the interior of the pole.

4. A pole comprising uprights, transverse bands having pockets toreceive said uprights, straps secured to said bands adjacent saidpockets, plural filling members for each pocket, said members having awedge configuration at the outer ends thereof to react against thestraps, and a separate wedge to expand said filling members for thepurpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
